GEORGE ERTEL, OF FORT WAYNE, INDIANA.

ClSTEFN-COVER.

Application led May 19,

Be it known that I, GEORGE ERTEL, a citizen of the United States, residing at Fort Yayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Oistern-Covers, and I do hereby declare that the following' is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

)Iy invention relates to improvements in cistern-covers.

The objects of my present invention are to provide a cistern-cover having a tapering cast-metal neck instead of the usual brickwall neck, thereby obviating the disintegrating effect of freezing of the mortar between the bricks and avoiding the necessity of the usual annular metal plate which rests upon the brick wall, and to which the cover is secured, and to provide a novel cap adapted for an interlocking engagement with the castmetal neck and having a novel form of adjustable slide adapted to snugly fit either a ive or a six inch pump-stock and also having the i angular central opening so constructed as to permit a proper turning of the pump to fit the opening when it is placed in position and also having a ventilating-opening in the means for securing the adjustable slide in position.

My invention consists of a cistern-cover having tapering open-ended metal neck, a circular cap adapted for an interlocking` union with the upper end of the neck, and having a radial opening to peririt the lateral adjustment of the pump-stock into position, an adjustable slide for the said opening and means for rigidly securing the slide in position.

Similar reference-numerals indicate like parts throughout the several views, in which- Figure I is a plan view of my improved cap, partly broken away to show the means for securing the slide in position and also showing in dotted outline the forward adj ustment of the slide to fit a five-inch pump. Fig. 2 is a vertical central section of my improved cap taken on the line of Fig. 1 with the adjustable slide removed. Fig. 3

is a vertical central section of my invention on the line y y of Fig. l, the metal neck being broken away in part. Fig. 4 is cross-section of the adjustable slide on the line .e 2 of Fig. 1, partly broken away, showing the means for locking the slide in position and also showing the ventilating means. Fig. 5 is a bottom plan of the plug which carries the interlocking means and showing the radial lugs by means of which the Ventilating-openings are provided. Fig. 6 is a detail cf the central opening in the cap, showing the opposite obtuse angles by means of which the pumpstock can readily be turned in adjusting it to position therein.

The cast-metal neck l, circular in crosssection and slightly tapering, as shown, is open at both top and bottom, has an outer peripheral flange 2 upon its lower end adapted to rest upon the top of the cistern, and is rigidly secured thereon by mortar in the usual manner, and has an inner annular flange 3 upon its upper end to aid in supporting and securing the removable cap about to be described. This ilange 3 has two diairetrically opposite vertical slots 8 for the purpose hereinafter described. v

The cap 4 is circular in contour,has a downturned perimeter 5, whose edge rests iirmly upon the top of the neck 1, and is provided with a pair of oppcsitely-arranged pendent lugs 6, having an outwardly-proj cctin g peint or hook 7, adapted for an interlocking engagement with the lower face of the flange 3, as shown in Fig. 3. The cap 4 has a radial opening 9, who se inner end tern^ mates in the right-angular sides 10, one of which ha s a vertical slot 11 for the usual slide to let the water of the pump-stock out to prevent freezing in a well understood manner. The parallel sides of this opening 9 have an upright longitudinal flange 12 and a pendent longitudinal flange 13, Fig. 4;.

A longitudinally-adjustable slide 14, having raised lateral longitudinal flanges 15, adapted to slidably rest upon the flanges 12, is adapted to close the opening 9 when the pump is in position. This slide 14 has its forward or inner end provided with the rightl angular sides 16, which in conjunction with l the respective opposite sides l0 of the opening 9 form a rectangular opening 17 for the pump-stock, Fig. 1, which, as shown, is i adapted to snugly fit a six-inch pump-stock,

ICO

and when the slide 14 is forwardly adjusted, as shown by the dotted outline, this contracted opening is adapted to snugly fit a five-inch pump-stock. The opening 17 of the cap has t'wo flaring sides 18, forming obtuse angles with the respective sides 10, Fig. 6, whereby when it is desired to either remove or replace the cap 4 it can readily be donelaterally, since the said obtuse angles permit the pump-stock to be so turned in the opening 17 as to readily pass through the opening 9. The slide 14 has a central opening surrounded by an upright flange 19. lIn this opening is loosely and rotatably mounted a plug 20, having an overhanging flange 21, provided upon its lower face with a plurality of pendent llugs 22, adapted to rest upon the flange 19, thereby leaving an air- Space between the same. On the lower angular end of this plug is mounted a latch 23, secured in positionby means of a pin 24 and adapted to normally engage the lower face of the flanges 13 to firmly secure the said slide in position.

The operation and manner of employing my invention thus described is obvious and, briefly stated., is as follows When the metallic neck 1 is employed instead of the usual cistern-neck of brick, it is apparent that it cannot be disintegrated or otherwise affected by freezing and also that it can be m ore conveniently and economically employed and also that when it is employed the use of the usual annular plate is avoided. The cap 4 is readily placed in position by first passing the opposite lugs 6 through the opposite slots 8 in the flange 3, after which the cap is given a sufficient turn to securely interlock the hooks 7 of lugs 6 with the flange 3. The pumpstock is neXt placed in position by passing it down through the opening 9 and then adjusting it in position in the opening 17, after which the slide 14 is placed upon the flanges 12 and then so adjusted that the sides 16 snugly abut the adjacent sides of the pumpstock, after which the plug 20 is rotated until the latch 23 is arranged transversely of the opening 9 anc in a holding engagement with the flanges 13.

Having thus described my invention and the .manner of employing the same, what I desire tc secure by Letters Patent is` 1. In a cistern-cover, a beveled tapering metal neck having a vertically-slotted flange on its upper end a cap having upon its lower face pendent lugs adapted to engage the said flange, and provided with a radial opening whose inner end terminates in right-angular sides; an adjustable slide or cover for the said opening whose inner end has angular sides to cooperate with the said angular sides to form a rectangular vertical central opening, and provider with means for rigidly securing the said slide in position. I

2. In a cistern-cover, the combination of an open-ended metal neck; a` circular cap having a radial opening and means for interlocking the same with the said neck; and an adjustable slide or cover for the said opening adapted to form a central angular opening, and provided with means for rigidly securing the same in position.

3. In a cistern-cover a circular cap having a radial slot or opening, and provided with means for securing the same in position; an adjustable slide or cover for the said opening; and means for rigidly securing the said slide in position.

4. In a cistern-cover a circular cap having a radial slot whose inner end terminates in angular sides, and opposite obtuse angles; an adjustable slide or cover for the said slot whose inner end is provided with angular sides for the purpose described g and means for rigidly securing the said slide in position.
